Line variable

The &Line variable contains the current print line number for a Procedure object at execution time. 
As it is a GeneXus built-in variable; &Line does not need to be defined.

Data Type:
Numeric (6)

Scope

Objects: Procedure

Notes:

• When generating in graphic mode this variable’s value is the length in pixels from the top of the page.
• Do not change the value of &Line, otherwise GeneXus will loose track of the paper ejection.
• When two programs have to share the same output; the variable &Line must be passed as a parameter between these programs.
• When a Report or Procedure receives &Line as a parameter, (&Line must be included in a Parm rule rule within the called program), the generated programs will have the following characteristics:
  • The first Header is not printed (It is assumed that it has been printed by the calling program).
  • If Ask functions are specified in the called program, they are performed only once, before beginning the data search
  • The default EJECT is not performed at the end of the called program.
  • Both programs (the called and the caller) must have the same values for PL, MB, and MT commands (PL is only considered when generating in text mode).
  • Both programs must be a procedures.
